PAINTING APPARATUS.

SPEGIFICATION forming part of Letters Patent K0. 769,372, datedSeptember 6, 1904. Application filed February 15, 1904:. Serial No.193,647. (No model.) I

To all whom, it may concern;

Be it known that I, JOHN J. ALLnN,a citizen of the United States,residing at Portland,

pertains to make and use the same.

' My. invention relates to an apparatus for applying paint, whitewash,or like substance to surfaces by the action of hydraulic pressure; andit hasfor its object the provision of an apparatus of this characterwhich shall be adapted fordealing with surfaces of considerable heightin a simple and eflective manner and with a great reduction of labor andexpense as ordinarily involved in such an op- Heretofore in all paintingapparatus of this particular type air has been used as the impellingagent, and in these instances it necessitates the provision of-a pump orother air-compressing means, thus greatly increasing the expense of theapparatus.

It is the purpose of the present invention to provide an apparatus whichshall be especially adapted for applying the paint by means of hydraulicpressure, in which case the apparatus may be connected directly to anyordinary water-main.

I T he invention is illustrated in the accompanying drawings, in which-Figure 1 is a vertical sectional view of the painting apparatus, andFig. 2 is a plan view of the same with the top of the tank almostentirely broken away.

Referring to the drawings, A denotes a suitable tank or other receptacleof any desirable size and capacity for holding the paint or likecomposition and containing the water under pressure, said tankbeingsufliciently strong to resist the pressure necessary to theejection of the paint. The tank-is provided at its top with acharging-orifice a, closed by a screw-plug a,'and at the bottom with adischarge-pipeb, to which. is connected a flexible tube 0, provided atits other end with any desirable spraying-nozzle or other applyingdevice. (Not shown.) The discharge-pipe b is provided with a valve orstop cock b for controlling'the'flow of the paint; but it will of coursebe understood that the spraying-nozzle may also be equipped withsuitable valves which shall be under the control of the operator fortemporarily checking the flow of the paint when desired and especiallyat a time when the operator a considerable distance from the tankforinstance, in coating surfaces of v considerable heightand at other timeswhen it would be extremely inconvenient for him i to cut off the flow bymeans of the stop-cock Z). The impelling agent, which in the presentinwater-main through the flexible tube cl, thence through pipes eandf,and finally admitted under pressure to the upper part of the tankthrough a number of branch pipes g. It will be noted that all of thebranch pipes g are provided with upturned spouts for directing the wateron its entry into the tank upward and away from the supply of paint.Owing to this arrangement of the inlet-pipes,it will of course beunderstood that the paint is not subjected to the full force of thestreams of water issuing from the branch pipes g, and thus undueagitation of the paint by reason of the incoming water is prevented. Asa further preventive of any undue agitation of the paint by the suddenforce of the water as it enters the tank and also for the purpose ofdistributing the downward pressure evenly over the entire surface ofthepaint I arrange within the tank 'a floating disk, said disk being of adiameter a little less than the interior diameter of the tank, so thatit loosely fits therein. The disk is preferably constructed of a bodyportion it, of wood, having embedded therein on opposite sides layers ofcork '5 a" to give the disk suflicient buoyancy to always keep itafloat.

as shown at f, and it is to be noted that the water issuing from thebranch pipes 9 will pass through all of these perforations, and thusexert an even pressure over the entire surface of the paint sufficientto eject the same from the tank. It is to be particularly noted thateven in the event the tank should be only half filled with thecomposition the force of the streams of water issuing from-the branchstance is water, is carried from any ordinary Numerous perforations areformed in the disk,

pipes 9 would be broken and the water spread over the entire top surfaceof the disk and allowed to pass through'all of the perforations thereinto evenly distribute the pressure over the entire surface of the saidcomposition. The paint or other composition, as the case may be, beingof a greater specific gravity than the Water and owing to the fact thatin the present apparatus there is provided suitable means fordistributing the hydraulic pressure at all times evenly over-its entiresurface, it will necessarily follow that thepressure within the tankwill force the paint out through the dischargepipe, where under thecontrol of the operator it may be directed onto the surfaces to becoated, it being understood that the valves have been previously opened.It is to be further noted that the discharge-pipe b is provided with apressure-gage 7:; of any wellknown type and that the tank has anordinary sigh t-glass Z suitably attached thereto near its bottom, bothof which being for obvious purposes. The tank is also provided near itsbottom and preferably at a point to one side of the discharge-pipe I)with a drawoif cock m, through which the water may be drawn andafterward used, if desired, in mixing the next coating composition.

In carrying out my invention various modifications in the constructiontherein shown and described may be made, and I would therefore have itunderstood that I do not limit myself to the precise details hereinillustrated.

Having thus described my invention, what I claim,is

1. An apparatus for applying paint or other composition to surfaces bythe action of fluidpressure, comprising a receptacle for holding thecomposition and receiving the fluid under pressure, a discharge-pipe forthe composition, and an inlet-pipe for the fluid having an upturned endlocated above the composition and serving to direct the fluid on itsentry into the tank upward and away from the c0mposition therein, I

2. An apparatus for ap ilying paint or other composition to surfaces bythe action of fluidpressure, comprising a receptacle for holding thecomposition and receiving the fluid under pressure, a discharge-pipe forthe composition, an inlet-pipe for the fluid, and a plurality ofupturned spouts connected to the inletpipe for directing the fluid onits entry into the tank upward and away from the composition therein.

3. An apparatus for applying paint or other composition to surfaces bythe action of hydraulic pressure, comprising a receptacle for holdingthe composition and receiving the water under pressure, a discharge-pipefor the composition, an inlet-pipe for the water, and means within thetank for distrilniting the hydraulic pressure evenly over the entiresurface of the composition.

4. An apparatus for applying paint or other composition to surfaces bythe action of hydraulic pressure, comprising a receptacle for holdingthe composition and receiving the water under pressure, a discharge-pipefor the composition, an inlet-pipe for the water, and afloatingperforated disk within the tank for distributing the hydraulic pressureevenly over the entire surface of the composition.

In testimony whereof I afiix my signature in presence of two witnesses.
